the moment of the German invasion, only four were manned: Wędrowiec (Traveller), Wąwóz (Gorge), Waligóra (Mountaincracker - name of a folk tale hero) and Włóczęga (Hobo). The fifth one, Wyrwidąb (also named after a folk tale hero) had to be abandoned due to lack of crews. The remaining 15 bunkers were at different stages of construction and most of them were little more than concrete foundations. The four bunkers were also only provisionally prepared. All of them lacked heavy machine gun (HMG) cupolas that were to be mounted on top of the ceilings to cover the battlefield with machine gun fire. There was neither electricity nor telephone network and the only means of communication were signal pipes, steel tubes with reflectors for Morse code communication, completely unusable in the dense smoke of the battle. The lack of electricity also resulted in the crew resorting to usage of kerosene lamps and candles, while the electric water pumps were not operational at all. Finally, the bunkers were insufficiently supplied with ammunition, which was to be delivered on 1 September but in reality never reached the troops. Opposing forces The four bunkers were manned with the 70 men strong 151st fortress company "Węgierska Górka" under the command of Captain Tadeusz Semik. The trenches around the bunkers were manned by the Border Defence Corps battalion "Berezwecz" under Major Kazimierz Czarkowski and the position was reinforced with two batteries of light artillery and one battery of mountain artillery from the 55th Light Artillery Regiment of the Polish 1st Mountain Brigade. In addition, the Polish forces were reinforced with small detachments of other units, among them two platoons of reserve forces of the "Żywiec" National Defence battalion and a small detachment of the mobilized Border Guard. Altogether, Captain Semik had roughly 1,200 men at his command. Against the Polish forces stood the entire German 7th Infantry Division, a part of the XVII Corps of the German 14th Army under Wilhelm List. The division, commanded by Major General Eugen Ott, was composed of three infantry regiments, reinforced with heavy artillery (150 mm). Altogether, the German commander had roughly 17,000 men at his disposal, more than ten times the number available to his opponent. Battle At half past 4 in the morning, on 1 September, the German 7th Infantry Division crossed the Polish border in the area of Milówka and started their assault towards the Polish positions. Their
